Blood test predicts spastic cerebral palsy

EurekAlert! - Jue, 06/21/2018 - 22:00
Researchers at Nemours and the University of Delaware have developed a blood test predictive of spastic cerebral palsy. Their study, published in BMC Bioinformatics, showed that DNA patterns in circulating blood cells can be used to help identify spastic CP patients (Crowgey et al.). New and better ways to identify infants with CP are needed so that interventions can start earlier for more children.

New social services for the elderly in modern Russian non-state social work

EurekAlert! - Jue, 06/21/2018 - 22:00
A team of Lobachevsky University researchers led by Professor Zaretkhan Saralieva is exploring the potential of social services for the elderly by public and religious organizations of modern Russia. Their work is focused on the transformation of social work with the elderly during the last four years in the context of contractual relations in social services and participation of socially-oriented non-profit organizations in the competition for state subsidies.

Decellularized cartilage-based scaffold promotes bone regeneration at fracture site

EurekAlert! - Jue, 06/21/2018 - 22:00
To help prevent possible complications such as nonunion at large fracture sites, researchers have developed a cartilage matrix that mimics the early stages of repair and provides the essential structural and biological properties needed by bone-forming cells to divide and grow.

People with schizophrenia account for more than one in 10 suicide cases

EurekAlert! - Jue, 06/21/2018 - 22:00
A new CAMH and Institute for Clinical Evaluative Sciences study shows that people with schizophrenia account for more than one in 10 cases of suicide in Ontario, and that young people are disproportionately affected.People with schizophrenia also had more contact with the health care system, pointing to an opportunity to intervene. The researchers emphasize the need for early suicide risk assessments to reduce risks.

Self-assembled energetic coordination polymers based on multidentate pentazole cyclo-N5-

EurekAlert! - Jue, 06/21/2018 - 22:00
In this work, guanidine cation CN3H6+ and 3-amino-1,2,4-triazole C2H4N4 were crystallized into NaN5 and two novel energetic coordination polymers (CPs), (NaN5)5[(CH6N3)N5](N5)3- and (NaN5)2(C2H4N4) were prepared respectively via a self-assembly process. The decomposition temperatures of both polymers increase to 118.4 and 126.5°C respectively. Moreover, no crystallized H2O was generated in products to afford the anhydrous compounds of pentazole salts as promising energetic materials.

Superconducting vortices quantize ordinary metal

EurekAlert! - Jue, 06/21/2018 - 22:00
Russian researchers together with their French colleagues discovered that a genuine feature of superconductors -- quantum Abrikosov vortices of supercurrent -- can also exist in an ordinary nonsuperconducting metal put into contact with a superconductor. The observation of these vortices provides direct evidence of induced quantum coherence. These fundamental results enable a better understanding and description of the processes occurring at the interface between superconducting and normal phases, which is important for future quantum technology.

The photoelectric effect in stereo

EurekAlert! - Jue, 06/21/2018 - 22:00
In the photoelectric effect, a photon ejects an electron from a material. Researchers at ETH have now used attosecond laser pulses to measure the time evolution of this effect in molecules. From their results they can deduce the exact location of a photoionization event.

UMBC researchers report novel method to quickly make therapeutic proteins from human blood

EurekAlert! - Jue, 06/21/2018 - 22:00
A new paper in Scientific Reports looks at how to extract cellular protein synthesis machinery from human blood, and, by adding recombinant DNA to the extract, to produce therapeutic proteins within two hours.

Origin Quantum Company and LQCC have successfully simulated a 64-qubit circuit

EurekAlert! - Jue, 06/21/2018 - 22:00
Origin Quantum Company cooperates with the team of Prof. Guang-Can Guo from the CAS Key Laboratory of Quantum Information, USTC (LQCC). They have performed a 64-qubit circuit simulation, and even revealed the possibility of a 72-qubit circuit simulation.

Important step towards a computer model that predicts the outcome of eye diseases

EurekAlert! - Jue, 06/21/2018 - 22:00
Understanding how the retina transforms images into signals that the brain can interpret would not only result in insights into brain computations, but could also be useful for medicine. As machine learning and artificial intelligence develop, eye diseases will soon be described in terms of the perturbations of computations performed by the retina. A newly developed model of the retina can predict with high precision the outcome of a defined perturbation.

Sex, drugs, and heart failure

EurekAlert! - Jue, 06/21/2018 - 22:00
Heart failure is almost as common in women as men, but its characteristics vary by sex. A new review summarizes the current state of sex-sensitive issues related to heart failure drugs included in treatment guidelines, and suggests future directions for improved care.

Mosquito-borne diseases in Europe: Containment strategy depends on when the alarm sets off

EurekAlert! - Jue, 06/21/2018 - 22:00
New research based on the Italian experience with outbreaks of Chikungunya, a disease borne by the tiger mosquito, in 2007 and 2017, shows that different vector control strategies are needed, depending on the time when the first cases are notified, 'thus providing useful indications supporting urgent decision-making of public health authorities in response to emerging mosquito-borne epidemics', Bocconi University's Alessia Melegaro says.

Miniature testing of drug pairs on tumour biopsies

EurekAlert! - Jue, 06/21/2018 - 22:00
Combinations of cancer drugs can be quickly and cheaply tested on tumour cells using a novel device developed by EMBL scientists. The research, reported in Nature Communications on June 22, marks the latest advancement in the field of personalised medicine.

Rapid and efficient oil-water separation achieved by newly-developed particles

EurekAlert! - Jue, 06/21/2018 - 22:00
Recently, researchers from the Technical Institute of Physics and Chemistry have developed an emulsion interfacial polymerization approach to synthesize anisotropic Janus particles with controllable topological and chemical anisotropy. This method can also be expanded to large-area fabrication of two-dimensional Janus film actuators.

Physical exercise improves the life quality of those living in care homes for the elderly

EurekAlert! - Jue, 06/21/2018 - 22:00
An exercise programme adapted to the capabilities of each person has shown how effective it is in improving the physical as well as mental health of elderly people who live in residential care homes. The UPV/EHU's Ageing-On research group, responsible for developing it, has prepared a strategy to be able to spread its application not just across care homes.

Digitalisation meets the Middle Ages

EurekAlert! - Jue, 06/21/2018 - 22:00
Smartphones and touchscreens could turn museum visits into a digital and multimedia experience. In the months ahead, an example of this can be seen in Admont Abbey in Austria. In a special exhibition, the abbey is presenting fragments of the 'Admonter Abrogans', a Latin-German dictionary from the period of around 800. The cultural treasures have been made accessible through a multi-media presentation, which researchers of the Institute of Creative\Media/Technologies at St. Pölten University of Applied Sciences (Austria) has designed.
